Microchip Technology's 25LC128-I/SM Serial EEPROM

The 25LC128-I/SM is a high-quality, 128-Kilobit (16,384 x 8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device from Microchip Technology. It utilizes the industry-standard Serial Peripheral Interface (SPI) to achieve fast data transfer rates, making it an excellent choice for a wide range of applications that require reliable and persistent data storage.

This EEPROM device operates over a broad voltage range (2.5V to 5.5V) and is characterized by its low-power consumption, which makes it suitable for battery-operated and power-sensitive applications. The 25LC128-I/SM features a page-write capability of up to 64 bytes of data, allowing efficient use of the memory for data logging and parameter storage.

One of the key benefits of the 25LC128-I/SM is its long data retention time, which is typically greater than 200 years, and a write endurance of over 1 million write cycles per byte. This ensures the reliability and longevity of the data stored in the device, which is crucial for mission-critical systems and applications where data integrity is paramount.

The device comes in an 8-lead SOIC (SM) package, which is known for its small footprint and is widely used in space-constrained environments. Its industrial temperature range (-40°C to +85°C) makes it robust and adaptable to harsh operating conditions, ensuring consistent performance across various environments.

Additional features of the 25LC128-I/SM include:

• Sequential read and write operations for streamlined data access
• Self-timed erase and write cycles with auto-erase before write
• Software write protection for full or partial memory array
• ESD protection up to 4000V, providing resilience against electrostatic discharges

With its combination of high-density, flexibility, and durability, the Microchip 25LC128-I/SM Serial EEPROM is an ideal data storage solution for a variety of electronic applications, including industrial automation, consumer electronics, medical devices, and automotive systems.
